As in the past, researchers from around the world will present their studies on various aspects of judo. It is a great time of intellectual and cultural exchange of ideas, opinions, and feelings about judo from a scientific and academic standpoint. This year is special, because we hope to formalize the creation of the International Association of Judo Researchers (IAJR). This association will help to legitimatize the work of judo researchers throughout the world, and bring mutual peace and harmony through the scientific study of judo. It has been my great pleasure to serve you and the IJF since 1998. I sincerely wish for the best for all of you in your scientific endeavors in judo, and for the success and prosperity of the IAJR in the future.
